Interactive exploration of near-infrared spectral signatures across crop types
Near-infrared (NIR) spectroscopy is a non-destructive technique that measures how plant tissues absorb and reflect light at different wavelengths. Each crop has a unique "spectral fingerprint" determined by its biochemical composition.
3,999 - 10,001 nm
Mid-infrared region sensitive to organic compounds
1,557 wavelengths
High-resolution spectral data per sample
Instructions:
The near-infrared (NIR) spectrum reveals chemical composition through molecular absorption:
Differences in spectral signatures between crops reflect their unique biochemical composition.
This spectral data forms the foundation of our machine learning models:
The ability to predict chemical composition from spectral data enables rapid, non-destructive assessment of crop nitrogen status in the field.
